I have Q10 Pro connected to AVR Denon X2300W
I listen a lot of HD Flac music with Himedia Music Plater.
I've just noticed that himedia device doesn't passthough music at 48 Khz, I've noticed this because of 2 things:
1) 5.1 flac 24/48 are downmixed to 2.0 to my AVR
2) When playing any 24/48 flac, I can adjust the volume with the Himedia Remote (I shoudn't be able if passthough was correct)
By the other side, if I play 24/96, 24/192, passthough works fine.
To listen 24/48 Multichannel audio I have to convert first to 24/96 with Foobar on my PC, then send to Q10 Pro.
I have the same issue with Android 7 (2.0.0) and Android 5.0 (1.0.9).
